y and solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou, says a lot of traffic jams (堵塞 ) will be reduced… The Super Bus can do the work of 40 buses. In that way, it can save 860 tons of fuel (燃料 ) 5 every year, according to Song. “ To build a Super Bus and its track costs less than building subways. Subways are nearly ten times more expensive to build.” Song said. Some people worry that the Super Bus may not be safe. However, Song says there‟s no need for concern. The Super Bus has laser scanners (激光扫描仪 ) between its legs. The scanners make sure the cars keep a safe distance. 根据短文内容，选择正确答案。 ( ) Super Bus can carry ________ people. A. 1,300 B. 1,500 C. 1,700 D. 1,900 ( ) the following are the advantages (优势 ) of the Super Bus EXCEPT that________. A. the bus doesn39。 t take up road space B. the bus can do the work of 40 buses C. the bus is very easy to build and drive D. the bus can save a lot of energy every year ( ) to Song, it39。 s safe for small cars to drive under the Super Bus because________. A. the bus is tall enough B. the road is wide enough C. there are scanners between its legs D. the bus travels at 60 km per hour ( ) can guess that Song39。 s purpose for building the bus was to________. A. take the place of small cars B. solve traffic problems C. increase the speed D. reduce car accidents ( ) passage is mainly about________. A. the normal bus B. the small car C. the subway D. the Super Bus (C) Get ready! Five, four, three, two, one, blast off(发射 )! With the last words, five rockets flew up into the sky. These were not real rockets taking off, though. They were model rockets made by students from Beijing No. 65 Middle School. Using the science knowledge they had learned in class, the students built the rockets all by themselves. Last week, students from different schools in Beijing also came to No. 65 Middle School to show off their good work at the opening of “Love Science Month”. It runs from the middle of October to midNovember. Besides rockets, students also showed off robots, model cars and other machines they had made. “Love Science Month” is very popular, for students can learn and have fun at the same time. On Monday, students from No. 35 Middle School saw some real airplanes at Beijing Aviation Museum(北京航空博物馆 ). They were very excited. “ I have seen the biggest plane here and the one that flies highest,” said junior(初级的 ) student Zhong Zhenping.“ I have learned a lot about planes here. I will study hard and bee a pilot when I grow up.” he said. There will be many other interesting science activities this month. Students will study space 6 and the history of spaceflight, and also take part in petitions. These will include making models of buildings, cars and planes. With Yang Liwei being China‟s first spaceman, students now want to know more about the science behind sending people into space. Tu Yuanhua, a teacher from Dongcheng Student Science and Technology Center said, “ ShenzhouⅩ has made students more interested in science. Through „Love Science Month‟, they are learning a lot about it.” 根据短文内容，回答下列问题。 rockets did the students make? ____________________________________________________________________ helped the students build the rockets? ____________。
